ABSTRACT:
There is provided a method of clipping a transmission signal. The method comprises: providing a residual signal of a complex envelope clipper based on the transmission signal to be clipped; providing a reference signal respective to the residual signal, the reference signal corresponding to an ideal residual signal; forming a clipping signal on the basis of the residual signal and the reference signal; subtracting the clipping signal from the residual signal for removing higher amplitudes of the residual signal; and subtracting the clipping signal from the reference signal for providing a reference signal respective to the clipped residual signal.
